Another fix my slice thread

[Addicted2Golf]

A couple of days ago I was able to get out to the range for the first time since the snow hit, and was a little bummed out when I was slicing the driver pretty bad. I was striking my iron's better than ever, and the ball flight was either straight, or a very slight push draw (I did a lot of work with my irons into a net through the winter). Today I went to a local golf shop and hit a few in front of the launch monitor. I was pushing the ball, and it had about 1200 rpm of side spin on it. The picture that was snapped was very revealing. The club face looked to be very very open.

I don't think that my slice is as much of a swing path issue as it is a club face issue. I've been working on staying centered over the ball much more which has helped my swing path. Does anybody have any tips on getting the club face to square up at impact? Last time I had this problem I tried to roll my arms over, which caused an OTT move which then caused a whole other bucket of problems. Can anybody help me with what it is supposed to feel like getting to the correct position? Any drills to work on specifically for the driver?
